Douglas Laboratories Melatonin P.R. 3 mg Prolonged-Release Bisected Tablets
Brand: Douglas Laboratories · Form: TABLET [E0155]
Our assessment
The evidence shows that this product, Douglas Laboratories Melatonin P.R. 3 mg, is a prolonged-release formulation designed to support sleep. However, the data provided does not contain specific information about melatonin itself. Our assessment is based on the available ingredient data for calcium, which is not the primary active ingredient in this supplement. For melatonin-specific guidance, data is not available.
How it works
Since the data provided focuses on calcium, we can describe its general role. Think of calcium as a structural building block for your bones and a signal carrier for your nerves and muscles. It supports bone density and mineral deposition, and it helps with muscle relaxation and nerve signaling [NIH ODS]. For the melatonin in this product, specific mechanism data is not available.
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. Based on the data for calcium, taking high levels can lead to constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. High calcium intakes might also increase the risk of heart disease and prostate cancer [NIH ODS]. For melatonin-specific side effects, data is not available.
Our recommendation
We recommend you use this product only as directed on the label. Because this is a prolonged-release tablet, do not crush or chew it. If you take any medications, be aware that calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For personalized advice on melatonin use, consult your healthcare provider, as specific safety data for this product is not available.
